We're pleased to present our Masked Man problem for March. The challenge is twofold; solve the problem, and identify the composer, who is pictured in the photograph above.

Here's the problem:

It's stormy today (March 15, 2005) in the mountains of New Mexico and our office has been closed for two days straight. Although The Checker Maven usually publishes on weekends, today is special, and we invite you to warm by the fire with this midweek bonus problem.

Can you see your way through this one? Stroke problems, artificial as the settings often are, make for great visualization practice. So, when you're ready, click on Read More to check your solution.

Sometimes in a checker game you try to achieve a certain position, formation, or situation; and at times it's just the opposite. That principle leads us to this month's first teaser.

Here's the layout:

Look easy enough? It's a bit easier than some others we've featured, but this one has been known to frustrate experienced players. Give a whirl, keeping the title in mind, and then click on Read More to check your solution. Were you able to ..... oops, we'd better not give it away!

We're continuing our long-term project of electronic republication of Willie Ryan's Tricks Traps & Shots of the Checkerboard with another pair of introductory problems. As usual, Willie's own inimitable commentary accompanies each. When you've worked out your solution, click on Read More to check your answers.
'Basic ideas never change, but they may occur on different areas of the board with more or fewer pieces involved. In Example 3, we have a snap layout of a double corner compound in which the winning plan is precisely the same as the one used in Example 2, but the arrangement of the pieces is different. A common fault of the beginner is his tendency to associate a particular tactical idea with only one position. This is undoubtedly an obstruction to progress. The main purpose of studying a problem position is to master the idea (or ideas) it illustrates so that the student may use it in any other situation where the same idea can be successfully applied.'
'One of the more spectacular fundamental principles is the "smother" idea. Example 4 frames an easy setting of a delayed smother coup in which first black's piece on square 22 is driven to a fatal spot (square 25), and then white makes two sacrifices in succession, winning by a weird tie-up. The description given to each example in this review of basic ideas is intended to help the reader to develop concepts of logical procedure. If we say "delayed smother" we mean the smother is not immediate, but that white can force black to make a certain move (or moves) that enables white to drive black into the coup position.'

The last offering for February is two problems in one. It's based on something published by Willie Ryan many years ago. The adaptation of the setting is rather liberal.

Here's the situation. You're in the final round of the Mega-Bowl of Checkers. The coveted title of Supreme Exalted Checker Champion hangs in the balance. Thousands of avid fans are watching from their $500 stadium seats and hundreds of thousands more are tuned in on the Checker Television Network. Sponsors have paid a million dollars each just for their 30-second commercial spots. This is really the Big Time, and you know if you win you'll become an instant media star, with wealth and fame yours without limit.

You're playing Black and it's your move:

The tension in the air is electric. Your five minutes are almost up. You've narrowed your choices down to two moves: 2-6, and 2-7. Somehow, you know that one of these moves will result in victory and a life of ease, while the other will lead to ignominious defeat and a quick return to your old back-breaking job at the quarry pits.

What move do you choose? Can you show how that move wins and why the other move loses?

Make your choice carefully; a lot is riding on it. Then take a look at the animated solutions in which Black wins or White wins.

Willie Ryan's Tricks, Traps, & Shots of the Checkerboard, published in 1950, is truly one of his best. Willie had as a goal the presentation of a graded compendium of tactical devices and examples, with shots and strokes the main feature, but various other motifs as well. By any measure, Willie succeeded rather well indeed.

This excellent book of tactics is extremely difficult to find at any price. Yet, it is such a valuable reference and training book for beginner and intermediate alike, that The Checker Maven has decided to produce, over a period of months, a freely available electronic version. (Recall that we did the same with Arthur Reisman's fine book of basics, Checkers the Easy Way, available in Postscript and PDF formats.) The copyright is long expired, and there are no legal or ethical barriers to republication.

We'll present a few pages in The Maven every few weeks, as mood and opportunity catches us; and we'll simultaneously gather it all together in what will eventually become a newly-typeset printable book.

Let's start off, then, with a pair of problems from the introductory pages of the book. We've called them Two Easy Pieces, and though these are speed-solvers for the experienced player, they present important basic concepts for the learner to master. Willie's own entertaining commentary accompanies each problem.

'A guileless amateur would be tempted to run for a king in Example 1, by moving 22-17; but black has a sure draw against that move by 7-11, 17-13, 11-16, 13-9, 16-19, etc. Instead of 22-17, white can make a win immediately by executing an elementary maneuver known as a "double exposure slip," which means that white can end all resistance by exposing two of black's pieces to capture at the same time. With this broad hint, the tyro should conceive the idea that gives black the heave-ho. A good plan for the beginner to adopt in studying a position is to allow himself a limited time, say five minutes, in which to find the right play without moving a piece; and failing in this, to consult the solution. This method enables the learner to correct his faulty calculations before they take root in his mind.'
'Again in Example 2, Mr. Tyro's policy of trying for a king by 18-14 is worthless, as black replies 6-9, 14-10, 13-17, 21-14, 9-18, with an easy draw in store. White simply does not have enough strength (placement of material) of position to make a strategic win, but in this case as in many others, a win can be effected by a tactical coup commonly termed "a compound stroke," so named because an opposing piece becomes an integral part of the scheme. In this example, we have the simplest form of a single corner compound in which the winning idea involves the single corner file or so-called "long diagonal."'

In January we presented a mind-boggler of a stroke problem (click here to see it again). This month, we offer another brain-twister of a different nature. Take a look at the situation diagrammed below, titled Remarkable Block Problem and attributed to an author calling himself "X.Y.Z."

Again, as in last month's stroke problem, the situation is artificial, but nonetheless diabolical. See if you can solve it without going off the deep end, and then take a look at the animated solution, here.

It all reminds us of Crowther's original Adventure game in which "you're in a maze of twisty passages..." But that was "XYZZY", not "X.Y.Z."

And, by the way, did you try to get your computer to solve this one? It's doubtful that any computer program would be able to come up with the solution. Click on Read More for some supplementary discussion on why this might be.

For the next little while, we'll be running a monthly "guess the author" feature problem. We'll present you with a checker problem, and a photograph; your challenge will be twofold:

1. Solve the problem (of course).
2. Identify the person in the photo (on the left), who is the problem's compositor. You can click on the photo for a full-size version.

February's entry will be what will probably turn out to be the easiest of the three, at least in terms of identifying the person in the photo; we're not so sure about the problem itself! Here it is:
